Schmit E speedo finaly work

Hi there,
Good news, the speedo work!
Here is what I found:
When you use the E start, the voltage to the speedo go down to 8 volts, result: the speedo go out.
Solution: a separate switch to feed the speedo, you start the engine, when the engine is runing switch the feed to the speedo.
Second problem: I use a sensor with 3 wires, the magneet is in the sensor, so you must use steel stuff to give the pulses, in my case I use the four bolts that hold the rear disk, big mistake, the four bolts have a head for a 17mm wrench, mutch to wide, this give a fals reading, the speedo was working but not accurate.
Solution: put the sensor 5mm backwards so the four bolts dont give any pulses anymore and put one 6mm bolt with a 10mm head.
After you do a drive to set over 1 km, and you know what? the speedo works and very accurate.
I you have a problem with a Smiths speedo, feel free to PM me, I will be more as happy
to try to help you
So long
Yves

Well done Yves. I bet you’re glad that’s sorted, I think it was starting to stress you out!

So... what’s next...?

Good Job! Only I've heard we should not use metric bolts on our bikes, only good Christian measured hardware should be used (joking!).

Stress give me the power to find the solutions, but I have to say the Schmit speedo was a real challenge
Next will be riding, the bike is ready, no oil leaks, fast and clean, just waything for the green light from the belgiam gouvernement
But as you know, there is alway a "next" on a Norton

Yves, thanks for the info. about the Smiths e-speedo.

When dealing with Matt from CNW he suggested mounting the three wire sensor I got from him with his bracket so it uses the 4 bolt heads that hold the rear disc in place (I've got a 75 MK3). He said he got much better & accurate results with the 4 bolts rather than using just one bolt, which is the opposite of your experience. I've no direct experience of this yet as I haven't installed the speedo.

I was pushing ahead with my own install but the speedo started to act up, when I got in touch with Smiths they confirmed the circuit board inside has a fault!!! I only bench tested it about 4 times!! They said they would replace the board but I need to send it back over to them! So the install is on hold for the moment.

Well done for sorting your own install, good to know you got it all working

Yves do you ride with lights on? If so, you could wire the speedo power to be on when the lights are switched on.

I know for sure that Matt is system will work; Matt never put something on the market if it don't work at 100%
The problem with Smiths is that the explains are not clear, at least for me, the Speedo and Tacho are very expensiv, so you can expect to have the things working
wish you good luck

Yes I ride with lights on, mandatory in Belgium, I start always the Seeley with the lights on, I do this to not forget the lights at daytime and to avoid a fine, thats why I put a separate switch to feed the Speedo
